Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine cool.
Disconnect the battery to prevent any electrical issues.

2. Identify and Repair the Leak

Sub-step 1: Locate the source of the oil leak by visually inspecting the engine components.
Sub-step 2: If the leak is from the valve cover gasket, remove the engine cover (if applicable) and remove the bolts securing the valve cover.
Sub-step 3: Replace the valve cover gasket with a new one, ensuring it is properly seated in the groove.
Sub-step 4: Reinstall the valve cover and torque the bolts to the manufacturer's specifications (typically around 10-15 Nm).
Sub-step 5: If the oil filter is found to be leaking, remove the old oil filter using an oil filter wrench and install a new one, ensuring the rubber O-ring is lubricated and the filter is tight.

3. Clean Up

Sub-step 1: Clean any spilled oil from the engine and surrounding areas using a degreaser.
Sub-step 2: Check the oil level again and top off with the manufacturer-recommended oil type if necessary.

4. Final Checks

Sub-step 1: Reconnect the battery.
Sub-step 2: Start the engine and let it idle while monitoring for any leaks and the burning smell.
